Last month, an "unknown creature" filmed climbing up an apartment building in Russia appeared on YouTube channel papotimes. You can watch the clip below.

If you dare.

And earlier this week, the video got a second wind, reappearing on another YouTube channel and website Before It's News as well as conspiracy forums (for example, here and here). Online, the creature is being called a "mutant" and being referred to as the Slender Man.

The video is creepy, that's for sure. But even forgetting for a moment that it shows a "mutant" climbing on a building, the clip does send off all sorts of alarm bells: Why is the person even filming the building before anything happens? Why is the quality so crappy? Why does the building look like a model? And why aren't the people filming it freaking out?
